SEQUENCE OF OPERATION:

START / STOP

HPCUs-1 AND 2: STARTED AND STOPPED AUTOMATICALLY RESPECTIVE OF PAIRED AHU. A COMPRESSOR CYCLES

DEPENDING ON COOLING AND HEATING REQUIREMENT.

AHUs-1, 2: STARTED AND STOPPED BY PROGRAMMABLE LEAD/LAG CONTROLLER WITH 'FAILURE' CHANGE-OVER.

OPERATING UNIT RUNS CONTINUOUSLY: 7-DAYS PER WEEK, 24-HOURS PER DAY, INCLUDING

WEEKENDS AND HOLIDAYS. SEQUENCING AND SCHEDULE ARE ADJUSTABLE.

COOLING

HPCUs-1, 2: IF COOLING SUPPLY AIR TEMPERATURE IS GREATER THAN SET-POINT, THEN HEAT PUMP SHALL RUN IN COOLING MODE AND CYCLE COMPRESSOR TO INCREASE COOLING UNTIL SET-POINT MET. ACTION

SHALL REVERSE AS SPACE AIR TEMPERATURE IS SATISFIED.

A 4 F (AFG) DEADBAND SHALL EXIST BETWEEN COOLING AND HEATING SUPPLY AIR SET-POINTS TO

PREVENT RESPECTIVE ACTIONS FROM HAPPENING SIMULTANEOUSLY.

COMPRESSOR HAS 2-STAGE OPERATION FROM 50 TO 100%. COMPRESSOR SOLENOID VALVE

UNLOADS COMPRESSOR TO PROVIDE STAGED OPERATION.

OUTDOOR AIR ECONOMIZER (FREE COOLING)

'OUTDOOR AIR ECONOMIZING' WILL INTRODUCE VARIABLE RATES OF OUTDOOR AIR TO MAINTAIN AN ENTERING MIXED AIR SET-POINT OF 60 F (ADJUSTABLE) WHEN OUTDOOR AIR TEMPERATURE IS LESS THAN (60 F ADJUSTABLE). OUTDOOR AIR DAMPER WILL CLOSE TO MINIMUM SETTING IF ENTERING

MIXED AIR TEMPERATURE REACHES 55 F.

HEATING

HPCUs-1, 2: IF SPACE AIR TEMPERATURE IS LESS THAN SET-POINT, THEN HEAT PUMP SHALL RUN IN HEATING

MODE AND CYCLE COMPRESSOR TO MEET SET-POINT.

IF SPACE TEMPERATURE IS LESS THAN SET-POINT AND HEAT PUMP IS OPERATING IN HEATING MODE, THEN AUXILIARY ELECTRICAL RESISTANCE HEATING ELEMENT SHALL ENERGIZE ACCORDINGLY AND HEAT SUPPLY AIR IN STAGES TO NOT LESS THAN 90 F, OR MORE THAN 110 F . ACTION SHALL

REVERSE AS HEATING SET POINT TEMPERATURE IS SATISFIED.

A 4 F (AFG) DEADBAND SHALL EXIST BETWEEN HEATING AND COOLING SUPPLY AIR SET-POINTS TO

PREVENT RESPECTIVE ACTIONS FROM OCCURRING SIMULTANEOUSLY.

VENTILATION

AHUs-1, 2: OUTDOOR AIR (OA) VENTILATION CONTROL IS SPRING CLOSED AND MOTOR OPEN. EXHAUST, MIXING, AND INTAKE AIR DAMPERS ARE CONTROLLED COLLECTIVELY BUT OPERATED

INDEPENDENTLY, USING INDIVIDUAL ACTUATORS. OA DAMPER SHALL BE INTERLOCKED TO OPEN TO

MINIMUM SETTING IF EITHER AHU IS RUNNING, AND CLOSE IF STOPPED. MINIMUM OUTDOOR

VENTILATION RATE IS 100 CFM, AND SHALL BE SET BY TEST & BALANCE.

SAFETIES

1. DE-ENERGIZED UNIT SHALL NOT SOUND ALARMS.

2. 'DIRTY FILTER': RETURN AIR FILTER SHALL BE MONITORED FOR EXCESSIVE DIFFERENTIAL PRESSURE. IF PRESSURE DROP IS GREATER THAN 'MAXIMUM' ALLOWABLE (ADJUSTABLE), THEN 'DIRTY FILTER' ALARM SHALL BE SENT. HOWEVER, 'DIRTY FILTER' CONDITION SHALL NOT BE HARD-WIRED INTERLOCKED TO STOP FAN - ONLY MONITOR AND SEND ALARM. NOTE: ANALOG INPUT READING OF 'MAXIMUM' ALLOWABLE DIFFERENTIAL PRESSURE MUST BE CORRELATED TO NORMAL AIRFLOW DURING TEST &

BALANCE.

3. FAN MOTOR PROVING: FAN MOTORS SHALL BE MONITORED FOR 'FAN FAILURE' BY BY ON-BOARD CONTROLLER USING CURRENT SENSOR ON MOTOR CIRCUIT, DIFFERENTIAL PRESSURE SWITCH ACROSS FILTER, AND/OR STATIC PRESSURE SENSOR IN SUPPLY DUCTWORK. IF MOTOR AMPERAGE IS LESS THAN NORMAL (ADJUSTABLE) AND PRESSURE DIFFERENCES ARE ZERO, THEN 'FAN FAILURE' ALARM SHALL BE SENT. NOTE: ANALOG INPUT FOR CURRENT COMPARISON MUST BE CORRELATED TO NORMAL DURING

TEST & BALANCE.

4. CONDENSATE PAN OVERFLOW: ALL UNITS SHALL HAVE INTEGRAL 'CONDENSATE' PAN OVERFLOW SWITCHES THAT SHALL ALARM IF WATER IS DETECTED IN CONDENSATE HI-LEVEL OUTLET OR AUXILIARY CONDENSATE OVER FLOW PAN.

5. HI-TEMPERATURE: IF SPACE OR RETURN AIR TEMPERATURE IS 5 F (AFG) ABOVE SET-POINT, THEN 'HI-TEMP' ALARM IS SENT.

6. LEAD/LAG CONTROL: AHU-1 AND 2 SHALL BE MONITORED FOR LEAD/LAG CONTROL AND EMERGENCY FAIL OVER. IF LEAD UNIT EXPERIENCES FAILURE OR HI-TEMPERATURE ALARM, THEN LAG UNIT SHALL BE ENERGIZED AND PREVIOUS LEAD DE-ENERGIZED.

7. EMERGENCY OUTDOOR AIR SHUT-OFF: AHU-1 AND 2 OUTDOOR VENTILATION SHALL BE EQUIPPED WITH MOTORIZED DAMPER CONTROL TO OVER-RIDE 'DAMPER-OPEN' COMMAND AND FULLY CLOSE DAMPER IF ACTIVATED. EMERGENCY OUTDOOR AIR SHUT-OFF SHALL BE MANUALLY CONTROLLED BY A PROTECTED 'EMERGENCY OFF' SWITCH LOCATED IN CAB.

8. FIRE: AHUs-1 AND 2 ARE A;READU EQUIPPED WITH SMOKE 'DUCT' DETECTORS IN SUPPLY AIR STREAM. EXISTING UNIT FIRE ALARM SEQUENCE SHUTS DOWN UNIT IF SMOKE IS DETECTED. MANUAL RESET IS REQUIRED IN EVENT OF ALARM.
